2 Claims. (or. 91-68) My invention relates to anew and novel mount- Fig. 4 illustrates a roll of metal foil in ribbon 'ing for gold or other precious metals in leaf or form with metal leaf secured directly thereto; powdered form particularly adapting the same Fig. 5 illustrates a roll of metal foil in which for use in heat embossing for the ornamentation metal leaf is secured thereto by an adhesive; and

' a of leather, cloth and other materials. Fig. 6 illustrates'a roll of metal foil in ribbon 5 Heretofore it has been customary to mount gold form in which a metallic powder is attached or other precious metal in leaf form upon a sheet thereto by means of an adhesive. or ribbon or tape of paper, attaching the metal to Referring to the drawing and first of all to Fig. the paper by suitable adhesive such as wax. 1, A represents a thin sheet of metal foil, preferto After the metal leaf is secured to the sheet or ably aluminum foil. This foil is of substantially l0 ribbon of paper, as the case may be, then a suitthe same thickness as that of paper upon which able size, such as French varnish, may be applied gold leaf is usually mounted. To one surface of to the surface of the metal. When heat and presthis sheet of metal foil is directly applied a sheet sure are applied by a die to a strip or sheet or" of gold leaf which is designated B. To the surmaterial so prepared the adhesive will be melted face of this gold leaf is applied a suitable size, 15 and permit the paper to be separated from the such as French varnish, and designated C. In metal leaf, the size causing the leaf to adhere to use, as will be appreciated, the sized surface of the surface being ornamented- On the other the leaf is appl ed directly to the leather, 610th hand the size may be applied directly to the suror other surface to be ornamented and a heated 29 face of the material to be ornamented instead of die pp to the back of the foil T heat to the surface of the metal leaf. of the die will cause the size to attach the leaf It has also been customary to mount various t the surf c b n ornam n d wh e p n he metals such as aluminum, bronze and other metals fo 6&1!- e pp Separated from the leaf in powdered form on paper sheets or ribbons or a d e a tapes by means of a suitable adhesive. After the I have found that the metal foil is very 25 surplus powder which does not adhere t th vantageous in this class of work in that it will paper has been removed then a suitable size is 01 01111 Imdfir t and y reason of its heat usually sprayed upon the powdered surface. Thi conducting characteristic, being an excellent conenables a powdered metal to be amxed to leather, ductor of heat, will greatly enhance the burnishcloth or other surfaces by means of a heated die as ihg efiect 011 the metal leaf- 3c in the case of metal leaf. It will be appreciated that the use of this foil One of the objects of my invention is to mount as a urt r advantage i that in the mounting metal leaf or metallic powder upon a support of of the leaf on the foil one step may be eliminated, metal foil, such as tin, lead, aluminum, etc, prefthat is t the s p in w h d s v i an- 5 erably aluminum foil, as l have found that th plied to the foil for the purpose of attaching the 5 use oi metal foil by reason of itsv heat conducting 1691f the foil, the embodiment of y invention and non-absorbent characteristics will greatly enas illustrated in 1 mounting the leaf directly hence the burnishing efiect of the metal leaf and O 151163 foilalso of the metallic powder to be applied to an In 2 I have Shown an embodiment of y g embossed surface. invention similar to that illustrated in Fig. 1, 4g

Another object of my invention is to provide a employing the metal foil A, gold leaf B and size suitable supporting or carrying medium for metal In t embodiment of y invention, wleaf or metallic powder that is not destroyed durv I v Shown an adhesive D for a ta hin ing the burnishing operation but can be reclaimed the 1883' to the vfoil- I have Obtained good results and used again. employing sour milk as the adhesive D, although at Other objects of my invention will appear from a material like paramn gives fairly good results. the detailed description that follows in which: In the form of my invention illustrated in Fig.

Fig. 1 illustrates metal leaf applied directly to 3 one surface of the foil A is coated with a suita sheet of metal foil; able adhesive D such as sour milk, for example,

so Fig. 2 illustrates an embodiment of my invenand on this adhesive I apply a metal powder E, tion in which a sheet of metal leaf is attached to such as aluminum, bronze and other metals, the a sheet of metal foil by an adhesive; surface of this powder having a size C such as Fig. 3 illustrates an embodiment of, my inven- French varnish, for instance, applied thereto. tion in which metal powder is attached to a sheet In use, with reference to the two embodiments 65 of metal foil by an adhesive; of my invention illustrated in Figs. 2 and 3, a hot die is applied to the outer surface of the foil A as before, the heat of the die not only burnishing the leaf B or the powder E, as the case may be, but causing the leaf or the powder to adhere to the surface of the material being ornamented,

the heat of the die also permitting of ready separation of the foil A from the leaf or the powder,

as the case may be.

I find when employing an adhesive between the metal and the foil that the non-absorbent characteristic of the foil is advantageous, the metal adhering to the foil more satisfactorily than when employing a backing or mounting, such as paper for instance, commonly employed in this art.

In Fig. 4 I have illustrated the foil F in ribbon form as distinguished from the sheet form of Figs. 1 to 3. The metal leaf G is mounted directly on one side of this foil and the surface of this metal leaf coated with the size H as in Fig. 1, for instance.

In Fig. 5 I employ foil F in ribbon form, the surface of this foil being coated with an adhesive I for attaching leaf G in ribbon form to the foil, the surface of the leaf G being coated with a suitable size H.

Fig. 6 is similar to Fig. 5 except that the leaf G has been substituted by a metal powder J, the surface of this powder being coated with suitable size H.

While I have pointed out in the various embodiments of my invention that a size is applied to the outer surface of the leaf or powder mounted upon the foil it is to be understood that if desired the size may be applied to the surface to be ornamented.

It will be appreciated that in use the foil will not be destroyed by the die as in the case of paper mountings but can be reclaimed, thereby avoiding the waste present when paper mountings are used.

What I claim is 1. As an article of manufacture for heat embossing thin aluminum foil having a surface coated with metallic powder secured thereto by a suitable adhesive.

2. As an article eof manufacture for heat em bossing thin aluminum foil having a surface coated with metallic powder secured thereto by a suitable adhesive, the powdered surface having a coating of a suitable size.
